Postal 2 is a first person shooter from 2003. It uses the Unreal Warfare (2.5) engine. It was developed by Running With Scissors but its distribution has been cloudy. Many publishers wouldn't touch it and those that did soon changed their mind.
Is this the game you're not supposed to play? Darker and more sadistic than Grand Theft Auto III, more action packed than Soldier of Fortune 2: Double Helix, more perverted than Manhunt, more... well, you get the idea. The game had a reputation among politicians who like to shine their image by trashing violent games. RWS tried to parlay this into bigger sales and failed. Miserably.
Why? Because quite simply the game sucks. SOF 2 and GTA 3 were big name entries that did gore and sandbox gameplay well. Manhunt, released the same year as Postal 2, was even more violent and perverted (arguably) and was a better game as well.
